Application led May 5, 1909. Serial No. 494,129.

To all whom it may concern:

Be it known that I, JOHN EwING SCOTT, a citizen of the United States,residing at Hillsdale, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements inHarrow-Eveners, of which the following is a specification.

This invention relates to harrows, and it has particular reference to animproved evener or draft equalizing device adapted to be used inconnection with a harrow that is composed of a plurality of sections forthe purpose of enabling` the harrow, including the evener or equalizerto be folded for the purpose of enabling the device to pass readilythrough an opening, such as a gateway, which is of a width less thanthat of the harrow when the latter is extended to its full capacity.

Other objects of the invention are to simplify and improve theconstruction and op-v eration of this class of devices.

lVit-h these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scopeof theinvention may be resorted to when desired.

In the drawing-Figure 1 is a plan view of a harrow constructed inaccordance with the invention. Fig. 2 is a view of the harrow folded forpassing through a gate. Fig. 3 is a detail plan view of the draw-bar andadjacent parts, the view being in elevation. Fig. l is a detailelevation of the draw-bar, showing the parts folded.

Corresponding parts of the several gures are denoted byv like charactersof reference.

For the purpose of illustration there has been shown in the drawings aharrow composed of three sections, viz: a central or middle section A,and two outer or side sections B and C. These harrow sections may be ofany suitable well-known and approved construction and they have beenshown asl being composed of frames including longitudinal frame-bars 5and cross-bars 6, said frames being equipped with suitably constructedearth-engaging teeth 7.

The evener is composed of a draw-bar D and two hitching-bars E, E, whichlatter are connected with the rear side of the drawbar by flexibleconnections consisting of `pairs, of eye-bolts 8, 8, which are linkedtogether as shown, the shanks of said eyebolts being fitted in suitableapertures in the members of the eveners where they are secured by meansof nuts 9.

The draw-bar D, comprises a central section 10, and two end sections 11,which are securely connected with the yends of the central orintermediate section 10 by means of hinges 12. Each of the hitching barsE is composed of a relatively long'outer section 13, and a relativelyshort inner section 14, which are connected together' by means of hinges15; the inner sections 14 are connected with the central or intermediatesection 10 of the draw-bar, near the ends of said central section, bythe flexible connections including the eye-bolts 8, 8; in like manner,that is to say by flexible connections composed of eye-bolts 8, 8, theouter sections 13 of the bitching-bars are connected with the outersections 11, of the draw-bar near the outer ends of said outer sections;the arrangement being such that the hinges connecting the sections 11with the sect-ion 10 of the draw-bar D, shall be in alinement with thehinges connecting the sections 13 with the sections 14, of the hitchingbars E.

The outer harrow sections B and C, are flexibly connected with the outermembers 13 of the hitching bars E, by means of eyebolts 16 or in anyother suitable and convenient and well-known manner; one harrow sectionbeing attached to or connected with each of the members 13; the centralharrow section A, is in like manner connected with the inner sections ormembers 14 of the two hitching bars E, E. In this manner a harrowbodywill be formed possessing great liexibilit-y and capability of adjustingitself to rough and uneven ground. The end members 11 of the draw-bar D,are provided adjacent to their inner ends where the hinges 12 arelocated with eyes or staples 17, which are connected by link rods 18,with a link or clevis 19, to which the draft may be attached; the eyes17 with which the link rods are connected may appropriately be formedupon the forward ends of the pintles 20, which serve to connect theleaves that combine with said pintles to constitute the hinges 12.

From the foregoing description taken in connection with the drawingshereto anneXed, the operation and advantages of this invention will bereadily understood by those skilled in the ait to which it appertains.It will be readily seen that one or both of the outer harrow-sections Band C may be folded or raised to a position above the central section A,thus greatly reducing t-he width of the harrow and enabling it to passthrough a gateway not greatly exceeding in width the width of a singleharrow-section. It is obvious that the improved construction of theevener enables the latter to be folded with the liarrow sections, asclearly indicated in the drawings. Vhen the hariow sections are extendedfor operation the evener will operate efliciently to equalize the draftupon the several sections, and the hinges or joints in the evener willenable the latter to iiex and yield when the harrow is passing overrough, hilly and uneven ground, thus furnishing a liarrow which will beparticularly adapted to oper- Y ate upon rough and hilly soil.

remaining sections being flexibly connected with the central member ofthe draft-bar; a liarrow section connected fleXibly with the twohitcliing-bar sections that are connected with the cent-ral section ofthe draft-bar; and harrow sections iexibly connected with the hitchingbar sections that are connected with the end-members of the draft-bar.

2. In a sectional harrow, an evener coniprising a draft-bar composed ofa central section and two end-members hingedly connected therewith; apair of hitching bars each composed of an inner member and an outermember hin gedly connected therewith, the inner' members of theliitching bars being iieXibly connected with the central member of thedraft-bar and the outer members of the hitcliiiig bars being flexiblyconnected with the end members of the draft-bar; a harrow sectionflexibly connected with the inner members of the hitcliing bars, andhai'row sections connected, one with each outer member of the hitchingbars; the hinges in the hitchiiig bars being disposed in longitudinalalinement with the hinges in the draft-bar, and the piiitles of thelatter hinges being provided with eyes at their forward ends.

In testimony whereof I affix my signature in presence of two witnesses.
